or this:

It installs fine on the computer downstairs. Same exact shit with a full cracked FL Studio 6. Version 5 cracked installs fine on my computer, but I don't want it because it's missing stuff and I want to try a newer version. I was going to buy the full version but I'm not going to even bother if there's a chance it won't even install. And I remember getting the same error a while ago when trying to install Winamp. I found out both use NSIS installer, but I can't really find any info on their forums that fixes my problem. The only difference between my comp and the one downstairs is the different hardware, obviously, and it uses XP SP1, where mine is SP2. Don't tell me that's it...I'm not wasting my time to put SP1.
I've tried deleting the folders that the install program makes. I've tried clearing out temp folders. I've tried using another hard drive and using different user accounts. I've tried re-downloading the file again and again, from multiple mirrors even. I've tried downloading the setup file on the other computer downstairs, burning it to a CD and using that to install. Nothing.

Anyone have any ideas? Thanks in advance...
